DSM melancholic features are unreliable predictors of ECT response: a CORE publication

OBJECTIVE: To determine the relationship between baseline melancholic features with outcomes in patients with major depressive disorder referred for electroconvulsive therapy (ECT). METHOD: In a multihospital (Consortium for Research in ECT) collaborative ECT study, SCID-1 interviews were obtained at study entry. Ratings of the 24-item Hamilton Rating Scale for Depression were obtained thrice weekly during the course of ECT, once during a subsequent treatment-free week, and periodically during 6-month continuation treatment with either bitemporal ECT or nortriptyline plus lithium (continuation pharmacotherapy). RESULTS: The evaluable sample was severely ill with a mean 24-item Hamilton Rating Scale for Depression score of 35.2 (+/-6.9). Of 489 patients, 63.6% (311) met DSM-IV criteria for melancholic features. During acute ECT, 62.1% of those with melancholic features remitted, as compared with 78.7% for those without melancholic features (P = 0.002). During medication continuation treatment (continuation pharmacotherapy), relapse rates were higher for those with melancholic features than for those without these features. Conversely, with continuation ECT, the rate of relapse was lower for those with, compared with those without, melancholic features. CONCLUSIONS: Ascertaining melancholic features by SCID-1 criteria does not identify depressed patients more likely to respond to ECT as had been anticipated from the literature. Melancholic features were associated with poorer treatment outcomes in acute ECT. Those with melancholic features were less likely to relapse with continuation ECT, but those with melancholic features were more likely to relapse with continuation pharmacotherapy. The limitations of the DSM-IV criteria for melancholia are discussed.     

A psychometric evaluation of the CDRS and MADRS in assessing depressive symptoms in children

OBJECTIVE: This study compared the psychometric properties of the Children's Depression Rating Scale-Revised (CDRS-R) and the Montgomery-Asberg Depression Rating Scale (MADRS) in children with major depressive disorder. METHOD: Children (N = 96; ages 8 to 11 years inclusive) with nonpsychotic major depressive disorder were enrolled. Participants were part of a multisite, outpatient, randomized, placebo-controlled, 9-week trial of fluoxetine (10 mg/day for the first week and 20 mg/day thereafter). The CDRS-R and MADRS were completed based on clinician interviews with both parents and children. Classic test theory and item response theory analyses were conducted. RESULTS: The MADRS and CDRS-R total scores were correlated at baseline (r = 0.51) and at study exit (r = 0.85). Cronbach's alpha was .86 (CDRS-R) and .82 (MADRS) at exit. The effect sizes for change from baseline to exit between the fluoxetine and placebo groups were 0.78 (CDRS-R) and 0.61 (MADRS). There was agreement between the CDRS-R and MADRS in the declaration of treatment response (50% improvement from baseline to exit) in 84.2% of children. Test information function favored the CDRS-R. CONCLUSIONS: The CDRS-R showed greater effect size for differentiating drug and placebo and better test information than the MADRS in this study of depressed children.     

Perceived unmet need for mental health care for Canadians with co-occurring mental and substance use disorders

OBJECTIVE: Previous analyses demonstrated an elevated occurrence of perceived unmet need for mental health care among persons with co-occurring mental and substance use disorders in comparison with those with either disorder. This study built on previous work to examine these associations and underlying reasons in more detail. METHODS: Secondary data analyses were performed on a subset of respondents to the 2002 Canadian Community Health Survey (unweighted N=4,052). Diagnostic algorithms classified respondents by past-year substance dependence and selected mood and anxiety disorders. Logistic regressions examined the associations between diagnoses and unmet need in the previous year, accounting for recent service use and potential predisposing, enabling, and need factors often associated with help seeking. Self-reported reasons underlying unmet need were also tabulated across diagnostic groups. RESULTS: Of persons with a disorder, 22% reported a 12-month unmet need for care. With controls for service use and other potential confounders, the odds of unmet need were significantly elevated among persons with co-occurring disorders (adjusted odds ratio=3.25; 95% confidence interval=1.96-5.37). Most commonly, the underlying reason involved a preference to self-manage symptoms or not getting around to seeking care, with some variation by diagnosis. CONCLUSIONS: The findings highlight potential problems for individuals with mental and substance use disorders in accessing services. The elevated occurrence of perceived unmet need appeared to be relatively less affected by contact with the health care system than by generalized distress and problem severity. Issues such as stigma, motivation, and satisfaction with past services may influence help-seeking patterns and perceptions of unmet need and should be examined in future work.     

Effect of ciliary neuronotrophic factor on somatostatin expression in chick ciliary ganglion neurons

The normal development of somatostatin (SOM) expression in neurons of the chick ciliary ganglion and the effects of ciliary neuronotrophic factor (CNTF) on SOM induction in cultured ciliary ganglion neurons, were studied by immunocytochemical techniques. SOM immunoreactivity was first detectable in some neurons of the ganglion at embryonic day (E)8 and between E14 to hatch, 44–46% of the neuronal population contained the peptide. It was inferred that essentially all choroid neurons, which constitute 50% of the neuronal population, contain SOM. Culture studies indicated that CNTF supported both the SOM positive choroid neurons and the SOM negative ciliary neurons. Although CNTF was necessary for the survival and maturation of cultured ciliary ganglion neurons, it did not influence either the induction or maintenance of SOM expression in these neurons. CNTF may instead act as a permissive factor, allowing the induction of SOM in neurons of the ciliary ganglion by other, more specific, factors.     

Recurrent carotid artery stenosis following endarterectomy.

Spectral analysis was used to examine 257 carotid arteries in 227 patients who had undergone carotid endarterectomy at 1, 3, 6, and 12 months after surgery and annually thereafter. Routine intraoperative completion angiography ensured that the operations were technically satisfactory. Postoperative restenoses were identified in 38 patients (15%). In 23 arteries (9%), the restenosis exceeded a 50% diameter reduction while in 15 arteries (6%) the stenosis was less than 50% of the diameter. Restenosis developed in 24/96 women (25%) and 14/161 men (9%). Twenty-nine (70%) stenotic lesions occurred within 12 months. In three patients early lesions regressed. Reoperation with patch angio-plasty was required in six patients. When the 219 carotid arteries that remained widely patent were compared to the 38 that restenosed , no differences were noted for age, diabetes mellitus, hypertension, smoking, or degree of preoperative stenosis. Early stenotic lesions appear to be due to myointimal hyperplasia, which is probably platelet mediated. The predominant female sex distribution may be explained by differences in platelet responsiveness in men and women.     

Development of a computerized assessment of clinician adherence to a treatment guideline for patients with bipolar disorder

The adoption of treatment guidelines for complex psychiatric illness is increasing. Treatment decisions in psychiatry depend on a number of variables, including severity of symptoms, past treatment history, patient preferences, medication tolerability, and clinical response. While patient outcomes may be improved by the use of treatment guidelines, there is no agreed upon standard by which to assess the degree to which clinician behavior corresponds to those recommendations. This report presents a method to assess clinician adherence to the complex multidimensional treatment guideline for bipolar disorder utilized in the Texas Medication Algorithm Project. The steps involved in the development of this system are presented, including the reliance on standardized documentation, defining core variables of interest, selecting criteria for operationalization of those variables, and computerization of the assessment of adherence. The computerized assessment represents an improvement over other assessment methods, which have relied on laborious and costly chart reviews to extract clinical information and to analyze provider behavior. However, it is limited by the specificity of decisions that guided the adherence scoring process. Preliminary findings using this system with 2035 clinical visits conducted for the bipolar disorder module of TMAP Phase 3 are presented. These data indicate that this system of guideline adherence monitoring is feasible.     

The Texas Medication Algorithm Project antipsychotic algorithm for schizophrenia: 2003 update

BACKGROUND: The Texas Medication Algorithm Project (TMAP) has been a public-academic collaboration in which guidelines for medication treatment of schizophrenia, bipolar disorder, and major depressive disorder were used in selected public outpatient clinics in Texas. Subsequently, these algorithms were implemented throughout Texas and are being used in other states. Guidelines require updating when significant new evidence emerges; the antipsychotic algorithm for schizophrenia was last updated in 1999. This article reports the recommendations developed in 2002 and 2003 by a group of experts, clinicians, and administrators. METHOD: A conference in January 2002 began the update process. Before the conference, experts in the pharmacologic treatment of schizophrenia, clinicians, and administrators reviewed literature topics and prepared presentations. Topics included ziprasidone's inclusion in the algorithm, the number of antipsychotics tried before clozapine, and the role of first generation antipsychotics. Data were rated according to Agency for Healthcare Research and Quality criteria. After discussing the presentations, conference attendees arrived at consensus recommendations. Consideration of aripiprazole's inclusion was subsequently handled by electronic communications. RESULTS: The antipsychotic algorithm for schizophrenia was updated to include ziprasidone and aripiprazole among the first-line agents. Relative to the prior algorithm, the number of stages before clozapine was reduced. First generation antipsychotics were included but not as first-line choices. For patients refusing or not responding to clozapine and clozapine augmentation, preference was given to trying monotherapy with another antipsychotic before resorting to antipsychotic combinations. CONCLUSION: Consensus on algorithm revisions was achieved, but only further well-controlled research will answer many key questions about sequence and type of medication treatments of schizophrenia.     

Influences of context, process and individual differences on nurses' readiness for change to Magnet status

Title.  Influences of context, process and individual differences on nurses' readiness for change to Magnet status.
Aim.  The aim of this study was to test hypotheses associated with a model which explains individuals' readiness in early stages of a change.
Background.  In an effort to improve the quality of nursing care, hospitals in the United States of America seek to obtain Magnet recognition. While it is commonly known that Magnet hospitals provide higher quality patient care, little is known about the variability in nurses' attitudes and behaviour within Magnet hospitals.
Method.  We collected data in 2006 from 310 Registered Nurses to investigate the factors that influence their willingness to embrace the changes necessary for the high levels of excellence accompanying Magnet status. Hierarchical linear modelling was used because the data were multi-level.
Results.  Both change-specific context, such as a culture of research exhibited by the manager, and formal education of the nurse moderated the positive influences of the organization's procedural justice actions. Specifically, procedural justice was stronger when the nurse manager demonstrated a culture of research, and negative effects of low justice were mitigated when nurses had a higher level of formal education.
Conclusion.  Preparing managers beforehand to appreciate and adopt new behaviours associated with a forthcoming organizational change should enhance the success of change practices as new changes are initiated. Moreover, education that exposes employees to the pending realities of their industry, such as nursing research, can play an important role in the development of positive beliefs about changes facing their organizations.     

Strengthening clinical effectiveness trials: equipoise-stratified randomization.

As psychiatric practice patterns evolve to take advantage of the growing list of treatments with proven efficacy, research studies with broader aims will become increasingly important. Randomized trials may need to accommodate multiple treatment options. In completely randomized designs, patients are assigned at random to one of the options, requiring that patients and clinicians find each of the options acceptable. In "clinician's choice" designs, patients are randomized to a small number of broad strategies and the choice of specific option within the broad strategy is left up to the clinician. The clinician's choice design permits some scope to patient and clinician preferences, but sacrifices the ability to make randomization-based comparisons of specific options. We describe a new approach, which we call the "equipoise stratified" design, that merges the advantages and avoids the disadvantages of the other two designs for clinical trials. The three designs are contrasted, using the National Institute of Mental Health Sequenced Treatment Alternatives to Relieve Depression trial as an example.
